Though ASHRAE recommends bringing in 15 cfm of outside air per occupant in a commercial building, a growing number of studies show that many U.S. schools are falling significantly short of that goal, which can translate to lower test scores, increased absences, and other health issues caused by poor IAQ.
It makes sense that monitoring energy consumption enables more control over the amount spent on energy. Doing this effectively, however, is not as simple as it sounds.
They are equipped with a built-in function that enables Internet connection (for example, a LAN network) to save users time by automatically uploading and displaying all the data on the Web.
In a paper recently published online in BMC Infectious Diseases, Koep and his fellow Mayo Clinic researchers explore humidity in schools and the potential effects it could have on the survival and transmissibility of the influenza virus.
Self-contained, the RTR-756 Wireless CO2 + Temperature + Humidity Data Logger is a flexible, real-time monitoring solution for managing CO2 levels, temperature, and humidity in schools and office buildings. The data logger features flexible recording and battery operation.
The data logger TR-76Ui-H is a three-channel recorder designed to simultaneously measure and record CO2 concentration, temperature, and humidity. The model achieves a temperature measurement accuracy of ±0.3°C between 10° and 40°. The accuracy is ±0.5°C at all other temperatures.
Matchbox-sized, the HOBO® UX90 motor on-off logger is an LCD-display data logger for monitoring run-times of motors, pumps, compressors, and other equipment. The logger provides a simple and convenient way to record up to 340,000 equipment on-off cycle changes.
The CO2 recorder TR-76Ui three-channel data logger simultaneously measures and records CO2 concentration, temperature, and humidity. The unit has a CO2 range up to 5,000 ppm and a capacity to store up to 8,000 data sets. The supplied software enables the user to download the data recorded.
